Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling display views of three-dimensional anatomical models during medical procedures, such as cardiac ablation, require manual intervention and communication between sterile and non-sterile fields, leading to inefficiencies and potential distractions for physicians.
Innovation Solution
An automated method for controlling display views of three-dimensional anatomical models based on catheter location and geometric features, using signals to adjust the display in real-time, reducing the need for manual adjustments and improving visualization efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control of display views is used, then the physician can adjust the three-dimensional anatomical model orientation, but it requires communication between sterile and non-sterile fields causing inefficiency and distraction
Solution Approach 1:
The system automatically controls the display views of the three-dimensional anatomical model based on catheter position data, eliminating the need for manual adjustment by the physician. The processor autonomously determines optimal viewing angles and updates the graphical user interface, allowing the physician to focus on the procedure without communication overhead.
Solution Approach 2:
The system continuously receives position data from the catheter and uses this feedback to dynamically adjust the display view. The processor monitors catheter location in real-time and automatically reorients the three-dimensional model to maintain optimal visualization, creating a closed-loop system that responds to procedural changes.
2Productivity
If automated display control is implemented, then procedural efficiency improves, but the system complexity increases
Solution Approach 1:
The processor performs multiple functions: it receives catheter position data, processes the spatial coordinates, determines optimal viewing angles, and updates the graphical user interface. This multi-functional approach consolidates what could be separate systems into a single integrated unit, managing complexity through functional integration.
Solution Approach 2:
The system combines the display control functionality with the existing catheter tracking system. The same processor that tracks catheter position also controls the display views, merging two functions into one system rather than adding a separate automated display control system.
3Measurement precision
If the display view continuously updates based on catheter position, then visualization accuracy improves, but computational processing increases
Solution Approach 1:
The system updates the display view based on significant changes in catheter position rather than continuously at maximum frequency. The processor determines when updates are necessary based on procedural context, performing partial updates only when needed to maintain visualization accuracy without excessive computational overhead.
